Mirror
I distinctly remember that bare-throated feeling of seeing my brother Jack's empty room the day after he left for college, that sense of losing my protector, my built-in companion, the one who always forged all the new paths a year before I did and then came home from kindergarten and taught me how to spell "dog" and "fish" before all the other four year olds.
I have a soft spot in my heart for the '10s because they're graduating with him, because again the thought of the seniors moving on to the so-called "real world" makes me feel vulnerable, like I've just been placed in an open field and the last line of defense has fallen.
I don't want to get too sentimental here, but if I have to reminisce about graduation, these are the thoughts that come to mind.
